Firm History
Our firm was founded in 1967 by patent attorney Karl Olbricht (Dipl.-Phys.) in Munich, Germany. In 1972, Mr. Olbricht moved the young firm to Weimar (Lahn), in close proximity to the university town of Marburg.
Starting from 1993, he began passing on his professional expertise and extensive experience on to the next generation. The individually run firm became a partnership under the name of “Olbricht & Buchhold Partnerschaft” when Jürgen Buchhold (Dipl. Phys.) completed his qualification as patent attorney in 1997.
Robin Keulertz (Dipl.-Ing.) began his career as a patent attorney under the supervision of Mr. Olbricht in 2005. Following the latter’s retirement, Mr. Buchhold and Mr. Keulertz pursued the partnership under the name “Olbricht Buchhold Keulertz Partnerschaft mbB” and opened a branch in Frankfurt am Main in 2009.
This branch became the main office when patent attorney Matthias Rathert (Dipl.-Ing.) joined the team in 2012. At the end of the same year, we acquired the firm of our late colleague Dr. Willi Schickedanz.
The start of 2016 saw the expansion of our firm into a second office in Essen, Germany in order to be able to provide more intensive support for clients from the Ruhr area in particular.
In 2019 the long-established law firm Pfister & Pfister from Memmingen has been acquired and since then forms our southern German location.
In 2020 we opened our new branch office in Hamburg under the management of patent attorney Dr. rer. nat. Sabine Kossak and are now also readily accessible in northern Germany.
Since 2023, the traditional law firm Habbel & Habbel from Münster (Westphalia) is part of Olbricht Patentanwälte, with the two patent attorneys Lutz and Peter Habbel.
